SC Pyrolysis oven

The extrud­ers for vert­ing are used for mate­ri­als that require degassing at the end of the melt­ing process—after the twin screw and the melt fil­ter. The melt flow is divid­ed into numer­ous small­er par­tial flows by the melt dis­tri­b­u­tion block in the entry area of the extruder’s spe­cial­ly devel­oped vent­ing screw. This increase in sur­face area enables par­tic­u­lar­ly effi­cient extrac­tion of the melt via the three vent­ing open­ings, using a vac­u­um sys­tem. This removes liq­uid, air, and impu­ri­ties in a pre­cise man­ner. The opti­mized melt flow can then be fed into fur­ther pro­cess­ing in the best qual­i­ty.

After vent­ing in the extrud­er, the sin­gle-screw extrud­er builds up the melt pres­sure nec­es­sary for the down­stream pel­letiz­ing process. This relieves the pres­sure on the upstream extru­sion and fil­tra­tion process­es and sig­nif­i­cant­ly increas­es the through­put and effi­cien­cy of the entire extru­sion line. The result: the high­est qual­i­ty at all pel­let lev­els for all con­ven­tion­al plas­tics.
